الفصل في صحة عضوية النائب بمجلس النواب األردني -قراءة في فلسفة النص وواقع الممارسة- Abstract,,, This study is concerned to look into the topic of the competent authority to decide the validity of the membership of the Hous e of Representatives in the Hashemite kingdom of Jordan, that research in two main axes: the constitutional articles and analyzing it, and the reality of practice of the authority, what is gotten confused and imprecation what to afflict the practice of overlap and confusion made it harder to resolve the problem of the first authority, to undertake the task of separation in validity of membership on the other side. As a matter of fact, we can admit that the idea of competent authority to decide the validity of the parliamentary membership can not be dealt away from the idea of power as a whole. Therefore, This approach must necessarily include the state authorities, with foxing on the theory of separation of authorities to guide us in this regard. Based on the above, the search in the legal jurisdiction of the membership in House of Representatives need to re-organize or create an integrated vision to ward off every tainted by confusion; to resolve the conflict of this power. conflicts which we mean here is a conflict between the two sides; the first is existed and immune to constitutional text, and the other is presumably a court to have jurisdiction over the validity of membership as a natural judge over all members of society. The realization of the principle of justice and equality may require to look at the judicial dispute about validity of parliamentary membership as the House of Representatives is a litigant or party in this dispute.
